An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-102027 in the wild and no public exploit code.\n\nAffected product: Juniper Networks Junos OS. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-102027/ (Markdown: https://insights.sbomify.com/CVE-2026-102027/index.md)","id":"CVE-2026-102027","markdown":"https://insights.sbomify.com/CVE-2026-102027/index.md","name":"CVE-2026-102027","record":{"aliases":["GHSA-57x6-37jg-h5f9"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Juniper Junos OS","requires_auth":"none","summary":"A configured eBGP neighbor can crash the routing daemon via crafted updates when multipath features are enabled, causing denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"juniper","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:L/AU:Y/R:A/V:C/RE:M","version":"4.0"},"cwes":[{"id":"CWE-131","name":"Incorrect Calculation of Buffer Size"}],"description":"An Incorrect Calculation of Buffer Size vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a configured eBGP neighbor to cause an rpd crash via BGP labeled-unicast UPDATEs when the affected multipath features are enabled.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Junos OS and Junos OS Evolved: A configured BGP neighbor causes rpd crash when multipath next-hops are processed","id":"CVE-2026-102027","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Junos OS and Junos OS Evolved: An attacker causes an rpd crash when VPLS auto-discovery is used","id":"CVE-2026-102028"},"packages":[],"prev":{"headline":"Junos OS and Junos OS Evolved: An attacker causes a routing-daemon crash when BGP RIB sharding is used","id":"CVE-2026-102026"},"products":["Junos OS","Junos OS Evolved"],"published":"2026-10-14","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-16","vendors":["Juniper Networks"]},"summary":"A configured eBGP neighbor can crash the routing daemon via crafted updates when multipath features are enabled, causing denial of service.","url":"https://insights.sbomify.com/CVE-2026-102027/"}
